Ludwig Wrap - is this black cortex or something else?

[Spoonman]

Hello Forum,
I bought this late 70’s early 80’s 6.5x14 snare the other day...rivets and all. Description was black cortex.
When I opened the box and looked at the wrap under the light, it almost looks like a dark mahogany cortex of sorts, but I cannot figure out what this wrap is called. It was not in the 1980. It does not appear to be faded as the color is consistent under the lugs. Any ideas?
Perhaps the glue bled thru and tweaked the finish, or the snare baked in the hot sun, and it broke down.
Photos are below, let me know if you have any idea on what it’s called or ideas on how the black cortex was transformed!

Looks like a rewrap to me.
DK for sure

Cortex is countertop laminate like Formica. To me that doesn't look like cortex as it appears too shiny. However if the rivets are in place that almost has to be a factory wrap though as no rewrapper was likely to re-install the factory rivets.

There was black and then there was black cortex. Cortex being a particular type of wrap material available in both solid and woodgrain colors.

If I remember right the 1984 catalog had a lot of finish options shown on the swatch page. I'll see if I can dig out my copy and see which potential choice that might be.
